Study on the Effects of Polygonum hydropiper,Mulberry Leaf and Polygonum multiflorum thunb leaf on Xiaoqu Quality

The effects of different ratio of polygonum hydropiper,mulberry leaf and polygonum multiflorum thunb leaf,culture time and culture tempreture on microbial species and quantity,saccharifying power,liquefying power,and ferementing rate of Xiaoqu were studied.The optimum technical conditions were determined by orthogonal test as follows: the ratio of polygonum hydropiper,mulberry leaf and polygonum multiflorum thunb leaf was 1∶1∶1 or 2∶1∶1 or 1∶2∶1,the optimum culture time was 5 d,and the optimum culture temperature was at 25 ℃.Under the optimum technical conditions,the saccharifying power,liquefying power and fermenting rate of Xiaoqu reached 480 mg/g·h,8.05g/g·h and 68.9 % respectively.
